A five gallon per minute KLeeNwater ELG demonstration unit was installed at a major utility to determine the most cost effective treatment program to meet ELG limits for either treat and discharge or zero liquid discharge (ZLD) scenarios.

Burner Vibration of an Oil Fired Industrial Air Heater
A mineral supplier with an industrial air heater used for spray drying was experiencing problematic vibration. After unsuccessful attempts to eliminate the vibration through tuning and OEM recommended changes, the customer contacted STEP for an onsite evaluation.

Combustion Diagnostic Testing
A utility boiler was de‐rated due to elevated opacity levels during high load operation. STEP was contracted to provide field diagnostics in order to evaluate the root cause of the elevated opacity as well as to provide an action plan for opacity mitigation and future preventative measures.

Sound Attenuation Analysis
A marine customer had to reduce the NOx emissions of a quad engine ferry utilizing a selective catalytic reduction (SCR) system. The SCR catalyst and housing would replace the existing silencer, and the customer needed to verify that noise levels would remain the same.

Transient Piping Analysis
A utility boiler was experiencing regular opacity spiking during start‐up, along with burner trips and instability. Recent operation as a peaking unit with a high frequency of starts and stops, the utility needed to improve the opacity and reliability during light‐off and warm‐up.
